I'm sitting at home today, because it is below freezing and we are supposed to get snow tonight. I don't want to spray new lawns for broadleaf in that weather. So, I notice one of my major competitors spraying one of my neighbor's lawns. Then a second truck pulled up. The first truck was spraying the neighbor's for broadleaf control and pre-emergent, as a new customer. The other truck was in the neighborhood doing all of the old customers pre-emergent. They had ~ 10 current customers in my neighborhood, and I would bet money they did not spray a single one of the retained customers. I don't know if they are supposedly spraying pendimethalin or prodiamine, but I could notice a tint on neighbor #1's house, which I know they actually sprayed. I noticed no tint on any of the others. Plus, i got down on my hands and knees, and I could not detect the slightest chemical odor. I am thinking of going door to door to those customers and telling them what I think their applicator did. but, i really don't want them calling this company and telling them that I was bashing them. i certainly don't want a war. Any way for me to know for sure if I am correct about them not spraying? What would you do?
